"Humans as Superorganisms: How Microbes, Viruses, Imprinted Genes and Other Selfish Entities Shape Our Behavior" by Peter Kramer and Paola Bressan discusses the idea that an individual homo sapiens is only one component of the human superorganism we call a person, focusing on the psychological and psychiatric ramifications thereof. (Paola Bressan previously.)
According to the American Society of Addiction Medicine, addiction is “a primary, chronic disease of brain reward, motivation, memory and related circuitry.” However, that’s not what the epidemiology of the disorder suggests. By age 35, half of all people who qualified for active alcoholism or addiction diagnoses during their teens and 20s no longer do, according to a study of over 42,000 Americans in a sample designed to represent the adult population.
Only a quarter of people who recover have ever sought assistance in doing so (including via 12-step programs). This actually makes addictions the psychiatric disorder with the highest odds of recovery.Metafilter's own maias on myths surrounding the disease(?) of substance addiction, and their impact on medicine and policy.
Your body is home to about 100 trillion bacteria and other microbes, collectively known as your microbiome. Naturalists first became aware of our invisible lodgers in the 1600s, but it wasn’t until the past few years that we’ve become really familiar with them. This recent research has given the microbiome a cuddly kind of fame. We’ve come to appreciate how beneficial our microbes are — breaking down our food, fighting off infections and nurturing our immune system. It’s a lovely, invisible garden we should be tending for our own well-being. But in the journal Bioessays, a team of scientists has raised a creepier possibility. Perhaps our menagerie of germs is also influencing our behavior in order to advance its own evolutionary success — giving us cravings for certain foods, for example.[more inside]

"Beyond the Brain" In the 1990s, scientists declared that schizophrenia and other psychiatric illnesses were pure brain disorders that would eventually yield to drugs. Now they are recognizing that social factors are among the causes, and must be part of the cure.
Falling STAR*D?: It is common practice for psychiatrists to switch depressive patients between different antidepressants if their current drug does not evince a symptomatic response. Despite clinical wisdom supporting this, little empirical, controlled evidence exists to direct “switching” protocols (e.g. if a patient with Z characteristics is on drug X, is it usually better to switch to drug A, B, or C? Will switching help at all?) in the psychopharmacological treatment of depression. The NIMH-funded STAR*D (Sequenced Alternatives to Relieve Depression) study aimed to address these questions of treatment direction in a very large (n>4000), “real-world” sample using a multi-phase treatment plan with different drugs (and cognitive therapy) at every step to maximize chances of eventual remission. Overall, the NIMH reported that about 67% of patients eventually achieved remission, with few differences in effectiveness between different types of treatment at each step. However, researchers and commentators have raised concerns regarding inconsistent reporting of outcomes, after-the-fact changes in study design and analysis, and other issues that may have inflated, partially invalidated, or misrepresented widely reported treatment outcomes. These inequities may also have implications for the secondary moderator analyses (i.e. does trait A predict switching to X or Y is better?) that were a major reason for the study. [more inside]
